How often should lead-acid batteries for fire alarm systems be charged and tested?

Lead-acid batteries for fire alarm systems should be charged and tested annually. This frequency aligns with industry best practices and safety standards, ensuring that the batteries maintain their capacity to function effectively during a power outage or emergency situation. Regular testing helps identify any potential issues with the battery before they can lead to failure, thereby ensuring the reliability of the fire alarm system.

While more frequent inspections (like monthly or quarterly) might seem prudent, they are typically not necessary unless specific conditions or manufacturer recommendations dictate otherwise. Annual testing provides a balanced approach to maintenance, ensuring compliance with regulatory requirements while managing operational efficiency.
